 genus of Eli/iid as a section of Cobresid comprising the species having one linear 

 Icrminal spike.

Rather common in moist, grass-grown, and irrigated places on the islets in Ihe 

 rivers Yenisei and Abakan, as well as in moist or irrigated depressions on the .\bakau 

 Steppe, near the river. Taken flowering in .Tune. Specimens taken in different loca- 

 lities vary considerably in the length and thickness of the culms. Near Askys I have 

 gathered a form with very slender and finely striped culms, about 40 cm. high. Hereby 

 it recalls /'. filiciilmis (Scnin.) A.schehs. et Graebn., but differs from the latter in its 

 large spilces, to 10 mm. long. In drier places the spikes become smaller, rounder, and 

 few-flowered. 



Distribution: Over the greater part of the globe.
